In 2010, Bruno Mars took over the pop charts, both as a singer ("Just The Way You Are," "Nothin' On You") and as a songwriter/producer (Cee-Lo, Mike Posner). In this clip, Mars — who's ringing in 2011 with a gig at the Renaissance Hotel in New York — talks to Rolling Stone about the wrestling-based origins of his name, shows off his Elvis impersonation skills and talks about the inspiration for some of his most popular tracks.
